Description

Technical Field

[0001] The utility model relates to the technical field of leather processing, in particular to a high-temperature foaming device for leather production. Background Art

[0002] Leather is a material made from processed animal skin. It is usually a product obtained by depilating, tanning and other processes the skin of animals such as cattle, sheep, and pigs. Leather is widely used in clothing, shoes, furniture, and automotive interiors.

[0003] High-temperature foaming devices for leather production are mainly used to make leather materials soft, tougher, and improve their texture through high-temperature treatment during the manufacturing process. These devices usually include high-temperature foaming machines, ovens, and other equipment. Among them, the high-temperature foaming oven for leather production is a device specifically used for high-temperature treatment of leather. By controlling the temperature and humidity in the oven, the leather can be shaped, dried, and softened. This helps to improve the quality and performance of the leather, making it more suitable for various application fields.

[0004] However, during the use of the foaming oven, the leather will produce odor after being heated and foamed. When the staff opens the foaming oven and takes out the leather in the oven, the gas in the foaming oven is too pungent, which has an adverse effect on the health of the staff. The pungent gas is directly discharged into the atmosphere and causes environmental pollution. Therefore, we propose a high-temperature foaming device for leather production. Utility Model Content

[0026] Working principle: before taking the foamed leather out of the oven body 1, first, connect the fan 2 5 to an external power source, so that the fan 2 5 can blow the airflow through the L-shaped tube 6 to the top of the tube body 19, and the sealing cover 9 on the tube body 19 will be blown upward (in this process, the three springs 11 between the sealing cover 9 and the annular plate 10 will be stretched), and the airflow will pass through the gap between the sealing cover 9 and the tube body 19 through the cylindrical tube 7 and blow to the air outlet pipe 8.

[0027] Then, the fan 13 is connected to an external power supply, and the fan 13 can blow the airflow to the sealing plate 13 through the L-shaped tube 4, and the sealing plate 13 will drive the three L-shaped plates 14 to move downward together, and the three L-shaped plates 14 will slide downward on the outer walls of their respective guide columns 15 (in this process, the springs 2 18 between the three L-shaped plates 14 and the annular plate 2 12 will be stretched on the outer walls of their respective guide columns 15), and the airflow will pass through the gap between the annular plate 2 12 and the sealing plate 13 and pass through the cylinder 2 into the interior of the oven main body 1, and finally reach the air outlet 8 through the tube body 19 and the cylindrical cylinder 7, and the activated carbon filter 17 on the air outlet 8 can filter the pungent gas inside the oven main body 1. After the filtering is completed, the power supply of the fan 13 and the fan 2 5 can be cut off, and under the action of the spring 11 and the spring 2 18, the sealing cover 9 and the sealing plate 13 will be reset, and the oven main body 1 can be restored to a sealed state, which will not affect the next leather foaming operation.
